CAUTION:
a. Do not bend or twist timing belt.
b. After removing timing belt, do not turn crankshaft and camshaft separately because valves will
strike piston heads.
c. Ensure that timing belt, camshaft sprocket, crankshaft sprocket and belt tensioner are clean and
free from oil and water.

Belt tensioner, tensioner spring and idler
1. Check belt tensioner and idler for smooth turning.
2. Check condition of tensioner spring.
Crankshaft sprocket and front camshaft sprocket
Check teeth for abnormal signs.
Installation
1. Confirm that No. 1 piston is set at TDC on its compression
stroke. (TDC is indicated by crankshaft pulley notch without
painted mark.)
2. Install tensioner and return spring.
Temporarily tighten bolts so that tensioner is set at the fully
outside position.
3. Install idler and tighten bolt to the specified torque.
4. Install timing belt with crankshaft sprocket.
a. Align white lines on timing belt with punchmarks on
camshaft sprocket and crankshaft sprocket.
b. Point arrow on timing belt toward belt cover.
5. Install camshaft sprocket plate and secure screws with Loctite.

6. Set No. 1 cylinder at TDC on its compression stroke. (TDC is
indicated by crankshaft pulley notch without painted mark.)
IMake sure that alignment marks of rear camshaft sprocket and
injection pump sprocket are positioned as shown.
7. Apply alignment marks on the back of timing belt according to
rear camshaft sprocket and injection pump sprocket alignment
marks. Also apply a front mark on the back of timing belt.
8. Loosen tensioner mounting nut. Using a screwdriver, turn ten-
sioner in direction of arrow to release belt tension.
9. Remove vacuum pump.
10. Remove timing belt.
INSTALLATION
